UNITED STATES J AMES G. WILSON, ,OF NEW CORRUGATED METAL ROLLING SHUTTER.

PATENT Fries.

SPECIFICATION forming part of Letters Patent NO. 296,373, dated April 8, 1884.

. Application filed December 22, 1883. (N model.)

T0 ail whom it may concern:

Be it known that I, JAMES GODFREY WIL- SON, residing in the city, county, and State of New York, have invented a new-and useful Improvement in Corrugated Metal Rolling Shutters, of which the following is a specification.

My invention relates to corrugated metal rolling shutters; and its objects are, first, to strengthen and protect those parts of the shutter which are most liable to wear; second, to deaden the noise which is usually caused in ter.

operating the same. I attain these objects by the construction shown in the accompanying drawings.

Figures 1 and 2 are edge views of my shut- Fig. 3 is a front view.

Similar letters refer to similar parts in each view.

a c are metal shields,formed to fit accurately the crown of the corrugation, and riveted through the shutter to pads or washers b b on the opposite side, of suitable form and material to allow of the movement of the shutter, the object being simply to prevent, when the shutter is being coiled or uncoiled, the corrugations catching in each other. The noise occasioned by this catching or slipping of the corrugations will thus be prevented, and at the same time the metal shields will protect the shutter wherever they are placed and prevent it from wearing out. The metal shields are preferably of the form shown on drawings, and about one inch in length; but I do not confine myself to this exact form or dimension. I preferto place these metal shields on both edges of the shutter, and on every a1- ternate corrugation. My invention, however,

will be employed if the metal shields are placed on every corrugation and on both sides of the shutter, or on corrugations farther apart. I propose, also, to use the shields for repairing and strengthening old shutters, for riveting on patches, or for covering up such small holes as time or accident may have .oc casioned.

I do not confine myself to any particular part of the shutter for affixing my shields, but intend placing them on any part where extra strength may be required.

I am aware that attempts have been made to prevent noise by the application to the edges of the shutter of leather strips or other soft material; and I am aware that Letters Patent were granted for such device on April 8, 1873, to Alexander Clark. My invention, however, is essentially different from this, inasmuch as I propose to prevent the noise in operating, and at the same time strengthen the shutter, by a device entirely different.

What I claim, and desire to secure by Letters Patent, is-

1. A corrugated metal rolling shutter hav- I ing its edges and those portions of its face or faces contiguous thereto protected and strengthened by means of superposed metal shields fitted to the crowns of individual cor- "rugations and individually attached, substantially as shown and described.

2. A corrugated metal rolling shutter having washers or pads fixed in the concavities of its corrugations, but not projecting beyond the crowns of its convex surfaces, substantially as shown and described.

3. The combinatiomwith a corrugated metal rolling shutter, of metal shields and pads, substantially as described.
